Sam and Bessie are in thier 80's. Sam always wanted an expensive pair of alligator shoes. Seeing them on sale one day, he purchases them and comes home, asking Bessie, "So, do you notice anything different about me?" "What's different, Sam? It's the same shirt you wore yesterday and the same pants. What's different?" Frustrated, Sam goes into the bathroom, undresses, and comes out completely naked, just wearing the new shoes. Again he says, "So, Bessie, do you notice anything different?" "What's different, Sam? It's hanging down today, it was hanging down yesterday, and it will be hanging down tomorrow." Angrily, Sam yells, "Do you know why it's hanging down? 'Cause it's looking at my new shoes!" Bessie replies, "You should have bought a hat."
